Application filed January 14, 1909. Serial No. 472,187.

To all whom it may concern:

Be'it known that I, WALTER S. ADAMS, a citizen of the United States, anda resident of the cit-y and county of Philadelphia and State ofPennsylvania, have invented a new and useful Improvement in Brake-Hangers, of which the following is a specification. The object of myinvention is to provide a device of this class which will automaticallycompensate for allwear and tear and adjust This object is accomplishedby my invention, some embodiments of which are described invention,reference is to be had to the accompanying drawings forming a parthereof, in which,

Figure 1 is a side elevation, partly in section, of one embodiment of myinvention. Figs. 2 and 3 show modifications.

- Throughout the various views of the drawings, similar referencecharacters designate similar parts.

In the embodiment of my invention shown in Fig. 1, my improved hanger 1is composed of two parallel and identical bars 2, each of whichis'perforated near each end and the wall of the perforation, in eachinstance, is provided with a curvature which is that of a sphere, orsubstantially this, as shown at 3. The parallel bars 2 are each mountedon and fit suitable brackets 4 and 5 secured to the transom 6' andbrake-arm 7, respectively, of a truck, in any suitable manner. Each ofthe brackets 4 and 5 is provided with-a bolt 8 'which. carries the usualthe bars 2 will have a slight universal movement on the brackets andwill always remain parallel and in proper relation. It is also obviousthat if desired, the bars 8 may be made integral With the brackets.

In the structure shown in Fig. 2 the bracket 12 is not perforated andthe arms 13 have suitable cups 1 1 to fit on the hemispherical ends 15of said bracket and extend beyond the same and are perforated to receivea bolt 16 which is provided with a nut 17, washer 18 and a coil-spring19. The tension of the bars 13 and the bracket 12 may be varied bytightening or loosening the nuts 17.

In the structure shown in Fig. 3, a further modification is made byplacing the bolt 16 on the other side of the bracket 12, so that thearms 13 do not have to be extended beyond the cups 14.

While I have shown and described certain embodiments of my invention, itis not restricted thereto, but is broad enough to cover all structuresthat come within the scope of the annexed claims.

What I claim is:

1. In a device of the class described, a pair of bracketshaving'hemispherical projections, a pair of parallel arms havingsuitable perforations fitting on said projectlons and-means for holdingsaid arms in place.

2. In a device of the class described a pair of brackets, each of whichis provided with projections having spherical surfaces, a pair ofparallel arms each of which is perforated at each end to fit on one ofsaid surfaces and bolts with springs thereon press- WALTER S. ADAMS.
